Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 25,565,467, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 25,565,467 | |
| -1 | -25,565,467 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,565,467.
Example:
1 x 25,565,467 = 25,565,467
and
-1 x -25,565,467 = 25,565,467
Notice both answers equal 25,565,467
With that explanation out of the way, let's continue. Next, we take the number 25,565,467 and divide it by 2:
25,565,467 ÷ 2 = 12,782,733.5
If the quotient is a whole number, then 2 and 12,782,733.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 25,565,467 | |
| -1 | -25,565,467 |
Now, we try dividing 25,565,467 by 3:
25,565,467 ÷ 3 = 8,521,822.3333
If the quotient is a whole number, then 3 and 8,521,822.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 25,565,467 | |
| -1 | -25,565,467 |
Let's try dividing by 4:
25,565,467 ÷ 4 = 6,391,366.75
If the quotient is a whole number, then 4 and 6,391,366.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 25,565,467 | |
| -1 | 25,565,467 |
If you did it right, you will end up with this table:
| 1 | 17 | 59 | 71 | 359 | 1,003 | 1,207 | 4,189 | 6,103 | 21,181 | 25,489 | 71,213 | 360,077 | 433,313 | 1,503,851 | 25,565,467 |
| -1 | -17 | -59 | -71 | -359 | -1,003 | -1,207 | -4,189 | -6,103 | -21,181 | -25,489 | -71,213 | -360,077 | -433,313 | -1,503,851 | -25,565,467 |
